I think that Bose audio components and systems are highly overrated. You seldom ever seem them rated in the top 10 of any car audio system reviews. Of course, your own ears are going to be your best guide for what sounds best for you. Perhaps having a graphic or parametric equalizer installed with your system would help a lot to fine tune it to your own tastes in frequency response.
Just watch that you don't get too much base. In a confined area like an automobile, it can be overpowering. And it can loosen up all your panels and fittings and give you buzzes and snapping that can drive you crazy. Low base frequencies should never have a buzzing noise in them. If you do, it means the signal is clipping from being overdriven.
Finding someone familiar with a C4 Corvette might be a challenge, but I think anyone competent with general car audio installs could figure it out for you. Problem is, you won't know who is competent until AFTER the work is done.
